Can the DC screen be charged with 220 volts for 380 volt charging?

This is not possible in this case, the main reason is that they are in a completely different situation, and if you charge it like this, it is easy to damage the machine.

The high-precision timing controller is used for intermediate relays. In addition, a three-phase contactor with a rated voltage of 380V and a control wire package of 220V is added. The opening and closing of the contactor is controlled by a time controller. The main contact of the contactor controls the three-phase equipment and it is OK.

I think it can be charged with 220V, because this voltage can also keep up, and it is possible to rush the sound a little slower.

If the port that asks for charging is 380 volts, it won't do anything if you use 220 volts to charge him. Must be powered by 380 volts.

It depends on whether the equipment parameters indicate 220 380V. If you don't, you can't. Just find the label and take a look.

Hello, this situation can also be used, but the charging speed is very slow, it is recommended to buy a matching one.

A: 380V AC, cannot be replaced by 220V AC.

If it is a three-phase four-wire 380V, it can be replaced by 220V AC.

The DC screen cannot be charged with 220 volts for 380 volt charging, because the voltage is too small to be charged.

The DC screen 380 can not be charged with 220 volts, after all, the voltage is different, and it is easy to burn out the equipment.

The DC screen 380 volt charging can be charged with 220 volts, but its working efficiency is higher than the general one.

If the power board wants to be repaired offline, this can be disconnected from his electricity first, and then its shell is removed, and then after dismantling, Jian Youpin will be able to see its motherboard, and after removing it, you can take off the machine for maintenance and stopping.

Hello! It states that the input voltage of the power supply is 110 volts at 50 Hz and 95 volts at 60 Hz. The output voltage is 12 volts and the maximum output current is amps (DC).

He stated that the load capacity of the power supply is voltant. (I personally think it's used in a foreign country).

If you want to buy it in our country, you can buy one with an input voltage of 220 volts, a frequency of 50Hz, an output voltage of 12 volts, and an output current (DC) greater than or equal to amperes.

Regarding the output voltage and current: when buying in China, it should be noted that its output voltage (unregulated) may be between 14 and 16 volts. It is best to energize the output with a resistor (3 ohms) to measure whether the voltage at both ends is between them. Otherwise, you have to think about it before you buy it.

Input voltage 110V, transformer capacity 95VA, use frequency range 50 60Hz output: 12V voltage current.

If you want to buy another 220V power supply.

Input 220v 95VA 50 60hz

Output: 12V

In the same way, the current, in addition to buying should be greater than less than or equal to?

Greater than", the current at the output terminal represents the output power, which must be larger than the original, otherwise the electrical appliance cannot work normally.

Input 110V working voltage 95VA input power is 95W 50 60Hz power supply frequency.

If I'm going to buy another 220V power supply.

For the purpose of protecting electrical appliances, but at the same time, the electrical appliances are required to work stably, what should be the output voltage?

To ensure 12 volts.

The output current can be greater than or equal to ampere, and it is also possible to be slightly less than, because the electrical power supply is designed with the power supply margin in mind, and it doesn't matter if it's smaller.

The input voltage is 110 volts, the input power is 95 watts, and the operating frequency is 50 to 60 Hz.

The output voltage is 12 volts, and the output current is amperes.

This must have been brought from Japan to China, because Japan's alternating current is 110V, and there are 220V to 110V transformers to buy them, and you can avoid unnecessary troubles caused by another transformer.

If you have to buy a 220V, then the output voltage must of course be equal to 12V, but it is okay to be slightly smaller, and the current is the same. If it is larger, it will affect the life of the appliance, while slightly smaller than the appliance can still work normally without affecting the lifespan.

In addition, buy a 220V power supply, the power should be 100 watts, to make the electrical appliances work stably, the output voltage should be equal to 12VThe current should be equal to.

The power supply operates at 35 degrees Celsius and is 300 watts.

260 watts at 50 degrees Celsius. It's all power ratings.

The maximum output is 300W, and the rated output is 260W, which is a small power supply for brand machines.

Unless there are special requirements in terms of anti-interference, etc., the mains power cord does not need to use shielded wires.

It is not necessary, the shielded ones are more likely to short circuit.

There is no need, the mains frequency is only 50hz, and there is no point in adding shielding.

The tungsten light is old and bad, try to change it to an LED light.

Is a computer a three-phase power plugged into the wall? You can take the power supply apart and take a look. Power off first.

It may be loose, and you can replace it with a new one, and it will be tight, and then it will be loosened. Take the power socket and look at it, it's just two bolts, and the cross flower is basically open.

Is the measurement voltage too high? If it is not convenient to detect for a long time, you can use a varistor to automatically detect the varistor, and the method is to buy a varistor voltage 470v (471) between the ignition wire and the ground wire, if the voltage is too high, the leakage protection will trip, if the non-voltage is too high, it is recommended to install a filter circuit in the circuit with intermediate frequency, and consider the possible high-frequency sharp pulse interference.

If this is the case, if it is not man-made, it is a problem with the circuit, then yes, you have aging electrical wiring, and the other one is yours, the house you rent, the circuit must be connected to a problem, you can find an electrician to help you.

Find someone to take a multimeter and measure whether the voltage is too high.

It may be that the line is aging, and the power of the electrical appliances is too large and overloaded.

It may be that the circuit is aging and there is a short circuit!

According to the situation you said, it is difficult to judge whether there is a problem, it is recommended that you find a multimeter to test whether your home's neutral live wire and grounding wire are normal, especially if you tell you that the voltage may be high, you check whether there is a problem with the voltage connection.

The bus is generally 10 square.

Copper core wire, 6 square copper core wire, 4 square copper core wire;

The distribution line generally uses a square power cord, the socket generally uses a square one, and the lighting circuit uses a square one;

Air conditioners within horsepower, or electrical appliances within 2000 watts, can use square copper core wire, larger power should use 4-6 square copper core wire, such as instantaneous electric water heater, the power is generally about 8000 watts, should use 6 square copper core wire is appropriate.

In addition, it also depends on the way the power cord is laid, the safe current size of the open wire laying and the dark wire laying is also different, and the electrical power divided by the voltage of 220 volts is the working current. For example, the power of the electric heater is 2000 watts, and the maximum working current is about 9A.

You see, 1 square wire (copper) conservative power can be used.

Change as much wire as your load is.

For 800w electrical appliances, it is best to use wires that are more than square millimeters.

Power = Voltage * Current. According to this formula, the current is obtained. (Know the power of the appliance first, the power divided by 220V = the required current of the appliance) The current passing through each square millimeter is about 3. The thickness of the required wire can be calculated.
